Hi Robert,
Thanks for using
Syncfusion products.
We have analyzed
your attached error message. We suspect that the references of the project are
of 11.103.0.21 version which in turn reproduced your reported issue. We suggest
you to confirm the references of the project are of 11.104.0.21 and also please
clear if you have any dll inside of bin folder, which also could be the cause
of the issue.
Please get back to
us if still could not resolve your reported issue.
Regards,
Ranjithkumar
